did you know that? it's true. scout's honor, it's true. now, have you checked it over the weekend? you have in your back, you have a little sack-- you have all these little bones like these. and as you keep going like this, walking along, boom, boom, boom, through the day... [laughter] at the end of the day, you're a little bit-- ever see those jogger types? they start off, "wow, let's go for a run, gang." and they run, boom, boom, boom. at the end of the day, "oh, boy, that was a good workout." [laughter] they get shorter. hey, it's true. you settle right down. and then at nighttime, you get in your bed, you--whooop... you come right back out again, you're all right, huh? now, i got something for you guys to check. i want you to check this out. tonight, before you hit the sack, i want you to find some part of your house that's just about out of your reach. find someplace where you can reach up and find a place-- like i used to have a room that had beamed ceilings, okay? and at nighttime, i could reach up and i couldn't touch those beams. reach, reach, i couldn't touch them.
